MADELEINE M. HILLS, OF NEW YORK, N. Y.

HORSE SHOE -PAD To all whom it may concern: ir Be it known that I,MADELEINE MERLI MILLS, a citizen of the United States, and resident ofKingsbridge, borough of the Bronx, city, county, and State of New York,have invented certain new and useful Imrovements in Horseshoe-Pads, ofwhich the ollowing is a speciiication.

My invention relates to horse-shoe ads and has for its obj ect toprovide a ad w'iich will aHord a permanently efficient old so as toprevent slipping and another object of my the bottom surface or treadsurface.

invention is to insure ventilation to the hoof when desired.

In the accompanying drawings Figure 1 is a longitudinal section showinga horses hoof with my improved pad applied thereto Fig. 2 is a sideelevation. Fig. 3 is a bottom view of the improved pad in connectionwith a horse-shoe. Fig. 4 is a vertical section on line 4-4 of Fig. l.Fig. 5 is a bottom view showing another form of my invention. Fig. 6 isa vertical section on line 6-6 of Fig. 5.

A indicates the horses hoof and B the horse-shoe, which may be of anystyle adapted for use in connection with pads.

The pad proper comprises an upper layer C made of leather, canvas, orother suitable material and adapted to be placed against the horseshoof. The tread portion D ofthe pad is formed of rubber or an equivalentcomposition and is provided with a number of recesses or openings Dleading upward from the bottom face of said tread portion. Some of theseopenings have been shown as holes registering with perforations C/ inthe upper layer C and preferably a layer of felt or other suitablematerial E is interposed between the two members of the pad at thepoints where such o enings lead through it in order that, while a owingfor ventilation, the passage of mud or grit to the hoof may beprevented. If desired, all of the openings through the pad might be ofthis character and in this case the grip or hold of the pad on thepavement is secured by a sort of suction or adhesion, slipping beingabsolutely prevented. The drawing shows that the majority or' theopenings D are filled with a gritty mixture F, which originally projectsslightly below This mixture consists of silicate of soda, or othersuitable binder, together with a gritty material, such as sandcarborundum or corundum in granular form or powdered and in someSpecification of Letters Patent.

cases I adniix fibrous asbestos to increase the tenacity of the mass.Such a gritty mixture will always remain rough, even after considerableuse, that is, it will not wear smooth and will therefore insure anabsolutely secure foothold for the horses. I prefer to'have theseopenings which contain the gritty mixture F, tapered or contractedtoward the bottom of the pad so as to guard against their slipping outof their sockets or recesses. The openings containing such grittymixture are preferably extended only through the ti'ead portion D, theupper layer C forming a covei' for said openings. When first made thepointsformed by the gritty mixture project slightly from the treadsurface.

The connection ol' the upper layer C and the tread portion D may beeffected in any suitable way, l'or instance by stitching along theperiphery as indicated at C2. It will be understood that all the holesmight be filled with the gritty mixture above referred to, or all oilthem might be lel't vacant, in which latter case only the suctionetl'ect would be relied upon to prevent slipping, or both el'- Vfectsmight be combined by iilling some of the holes and leaving others empty,as shown in Figs. l and 3.

In Figs. 5 and 6 I have shown a slightly different construction in whichall the holes of the tread portion D2 are filled with a gritty mixtureand preferably these holes are not only tapered toward their' lowerends, but also inclined as shown in Fig. 6. The upper layer C3 ol' thepad is slightly diiiierent in shape irom that shown in Fig. 3 having acut or 'fissure C at the rear end or heel to secure a better iit andgreater elasticity. The line ol' stitching C5 Afollows the outline ofthe upper layer C3.

Instead ol' sewing the two portions of the pad together, they might bewelded or connected in any other way. The cellular structure obtained bythe vacant holes and the suction effect resulting therefrom may beemployed in connection with any foot-wear i'or horses and the same thingis true ol' the gritty mixture applied to roughen the tread surface.

I claim as my invention 5 l. A horse-shoe pad comprising an upper layer,an elastic tread portion secured to said layer and provided withventilating perforations, and a barrier, pervious to air, closing saidperforations.
